"They're not like the hardest descents around, so if you're experienced... and you're keen, you can do all those descents."

But of course, before you can witness the descents, you've got to tackle the climb.

"It's fairly technically challenging climbing, because you're always on single track and there's a lot of tight corners and rocks to get up and over, but the thing that makes it the hardest is that the grades are really quite steep," Evans said.

The total average grade on the way up is about nine per cent, Evans said, but for a prolonged stretch you're looking at a grade of close to 20 per cent.

"There's pretty much no way you can go up there without really breaking a sweat," he said.

"And then the fact that you have to do that three times makes it quite the accomplishment just to finish this."
